A Certificate of Deposit Is a Savings Account That Locks Your Money Away for a Set Time

A certificate of deposit, or CD, is a savings product offered by banks and credit unions. You give the bank a sum of money—say $1,000 or $5,000—and agree to leave it untouched for a fixed period. In exchange, the bank pays you a higher interest rate than a regular savings account would. When the time is up, you get your original money back plus the interest earned.

The trade-off is straightforward: you cannot touch the money without a penalty. If you withdraw before the term ends, the bank charges a fee that eats into your earnings. That penalty is why CDs pay more than savings accounts—the bank knows your money will stay put, so it can lend it out with confidence.

CDs come in different lengths. A bank might offer three-month, six-month, one-year, two-year, or five-year terms. The longer you lock your money away, the higher the interest rate usually is. A one-year CD pays more than a three-month CD at the same bank.

Key Takeaways

  • A CD pays a fixed interest rate in exchange for agreeing not to withdraw your money until the term ends.
  • Early withdrawal penalties can wipe out most or all of your interest earnings, so only use a CD for money you will not need soon.
  • Interest rates vary by bank, by term length, and by the amount you deposit—shopping around can mean hundreds of dollars in difference.
  • When your CD matures, the bank will either return your money or automatically roll it into a new CD at the current rate unless you tell them otherwise.

How Interest Rates and Terms Work Together

Banks set CD rates based on what the Federal Reserve is doing with interest rates. When the Fed raises rates, new CDs pay more. When the Fed cuts rates, new CDs pay less. This means the rate you lock in today is only good for that specific CD—when it matures, you may get a lower rate on the next one.

The term length matters because longer commitments usually pay more. A five-year CD might pay 4.5 percent annually, while a six-month CD at the same bank might pay 4.0 percent. The bank is paying you extra because you are giving up access to your money for longer.

The amount you deposit can also affect the rate. Some banks offer higher rates on larger deposits—$25,000 or more might earn a slightly better rate than $5,000. Check the specific terms at your bank or credit union.

What Happens When Your CD Matures

When the term ends, your CD reaches maturity. The bank sends you a notice a few weeks before, telling you what will happen next. You have a choice window—usually five to ten days—to decide what to do with the money.

You can withdraw the full amount (principal plus interest) and move it elsewhere. You can open a new CD at the same bank, possibly at a different rate and term. Or you can move the money to a savings account or another bank entirely. If you do nothing, most banks automatically roll the money into a new CD at the current rate for the same term length—a process called auto-renewal. Read the maturity notice carefully so you are not surprised by auto-renewal.

Early Withdrawal Penalties and When They explore

If you need the money before the term ends, the bank will charge a penalty. The penalty amount varies widely—some banks charge three months of interest, others charge six months or a percentage of the deposit. A $10,000 CD with a six-month penalty might cost you $150 to $300 to withdraw early, depending on the rate.

The penalty is deducted from your earnings first. If you have earned $200 in interest and the penalty is $150, you get back your $10,000 plus $50. If the penalty is larger than your earnings, you lose money from your original deposit. This is why CDs are only for money you are confident you will not need.

Some banks offer "no-penalty CDs" that let you withdraw without a fee, but they pay lower interest rates in exchange. These are useful if you want the higher rate of a CD but need some flexibility.

Where to Find CDs and How to Compare Them

Most banks and credit unions offer CDs. You can open one in person at a branch, online, or over the phone. Online banks often pay higher rates than brick-and-mortar banks because they have lower overhead costs.

To compare CDs, look at the annual percentage yield, or APY. This is the actual return you will earn over a year, including compounding. Two banks might advertise the same interest rate, but one compounds daily and one compounds monthly—the APY tells you which one pays more.

Check multiple banks before deciding. The difference between a 4.0 percent APY and a 4.5 percent APY on a $10,000 one-year CD is $50 in earnings. Over five years, that gap grows much larger. Websites that track CD rates can help you see what banks are currently offering.

CDs Are FDIC Insured Up to a Limit

Money in a CD at a bank is protected by the Federal Deposit Insurance Corporation, or FDIC, up to $250,000 per depositor per bank. If the bank fails, the FDIC returns your money. This protection covers the principal and any interest earned up to the $250,000 limit.

Credit unions offer similar protection through the National Credit Union Administration, or NCUA, also up to $250,000. This means your CD is safe even if the institution fails—you will not lose your money.

If you have more than $250,000 to invest, you can open CDs at multiple banks to stay within the insurance limit at each one. Some people use this strategy to keep large sums safe while earning CD rates.

CDs Versus Other Savings Options

A regular savings account is more flexible—you can withdraw anytime without penalty—but it pays much less interest. A high-yield savings account pays more than a regular account but usually less than a CD. Money market accounts offer a middle ground with some check-writing ability but lower rates than CDs.

If you have money you will not need for six months or longer, a CD usually beats a savings account. If you might need the money sooner, a high-yield savings account is safer because there is no penalty. If you want to invest for growth over years, stocks or bonds might be better, though they carry more risk than a CD.

The right choice depends on when you need the money and how much risk you are willing to take. CDs are for people who have a specific time horizon and want a may provide return.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty that reduces your earnings or even your principal. The penalty amount depends on the bank and the term length. Some banks offer no-penalty CDs that let you withdraw without a fee, though they pay lower rates.

What is the difference between APY and interest rate?

The interest rate is the percentage the bank pays. The APY is the actual return you earn after accounting for how often the bank compounds interest. APY is always equal to or higher than the stated rate, so compare APYs when shopping for CDs.

What happens if I do nothing when my CD matures?

Most banks automatically roll your CD into a new one at the current rate for the same term length. This is called auto-renewal. You will receive a notice before maturity telling you this will happen, and you can contact the bank to withdraw or move the money instead.

Is my money safe in a CD?

Yes, CDs at banks are insured by the FDIC up to $250,000, and CDs at credit unions are insured by the NCUA up to $250,000. If the institution fails, you get your money back. This protection covers both your principal and interest earned.

Do I pay taxes on CD interest?

Yes, CD interest is taxable income. The bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return. Some people use CDs in retirement accounts like IRAs to defer taxes on the interest.
